"Last week I had the first of two appointments for the replacement of a crown.  I was amazed that I did not feel even the initial stick of the injection, and the entire process was comfortable and painless, even when the numbness wore off.  Many thanks to Dr. Sayeg for his skill and calm, easy manner and Shinny for her warmth and professionalism.  For her congeniality and gentle touch during all of my dental cleanings, I thank Tanya.  And Rebecca is to be commended for being efficient and ever-pleasant, with a ready smile in person that can even be heard through the telephone. With such caring staff, access to my favorite shows on Netflix and Hulu, and paraffin hand treatments, this office makes dental visits feel almost like trips to a day spa!"



"Wonderful! Nicest patient people in the world! They make you feel like you are the only patient. Dr. Sayeg is a very talented dentist. They do their best to keep you confortable and smiling! Thank you!"



"My husband and I are thrilled to have found Dr. Sayeg and Start Smiling Dental! We are treated in a friendly, professional and knowledgeable manner by the entire staff each time we have an appointment. We especially appreciate that Dr. Sayeg and his staff approach each problem conservatively rather than pole vault to an aggressive solution when it isn't necessary.The waiting and treatment areas are welcoming, clean and bright, adding to patient comfort. We've found our new dental home!"



"Love Dr. Sayeg and the whole team at Start Smiling. Every time I visit, everyone in the office is friendly and accommodating. They are incredibly knowledgeable and consultative, and do consistently wonderful work."
